China approves a second COVID-19 vaccine
By Sui-Lee Wee
Beijing has approved a second Chinese COVID-19 vaccine — a drug made by Sinovac Biotech that will be distributed to developing countries — in a move that furthers the country’s efforts to be a global player in ending the pandemic.
Sinovac said in a statement Saturday that it had received conditional approval from China’s National Medical Products Administration a day earlier. In December, China approved a vaccine made by Sinopharm Group, a state-owned company.
Sinovac and Sinopharm have released little data from late-stage trials that would allow scientists to draw independent conclusions on their vaccines’ efficacy. Sinovac’s vaccine, CoronaVac, has had four different efficacy rates announced in recent months by the countries that conducted Phase 3 trials. In the most recent, Brazilian officials said that CoronaVac had an efficacy rate of just over 50%, although those who received it and still became infected showed only “very mild symptoms.”
Sinovac said the approval was based on two months of clinical trial data. It said it had not obtained the final analysis data, adding that “the effectiveness and safety results have yet to be further confirmed.”
Sinovac has struck deals with at least 11 countries and regions, including Brazil, Chile, Indonesia and Turkey, in keeping with President Xi Jinping’s promise last year that a Chinese COVID-19 vaccine would be a global public good.
Sinovac said it had completed a second production line that would increase its manufacturing capacity to more than 1 billion doses after it is put into use this month.
Even before the completion of late-stage trials, Chinese officials approved the vaccines from Sinopharm and Sinovac for emergency use and rolled them out to millions of people, prompting criticism from scientists who argued that the move could pose a risk to public health.
